The death of Coos Bay murder victim Linda Foley remains under investigation as Oregon State Police Crime labs review DNA and blood samples to assist in the case.

Coos County District Attorney R. Paul Frasier said crime labs are attempting to determine if blood on suspect Henry L. Cozad's pants and shoes is consistent with blood splatter or blood smears. Cozad, 18, is the only suspect in the case.

"At this point I have no evidence to suggest anyone else was involved," the DA said.

If investigators ascertain that Cozad's clothing has evidence of high impact blood splatter, it would indicate his presence when Foley was beaten. A blood smear, on the other hand, would be more consistent with the suspect kneeling by Foley's body. Results are expected in six to eight weeks.

Additionally, a theory presented by Cozad's father, Fred Cozad, that Foley tripped and fell into a welder inside their home doesn't hold water, Frasier said. Her injuries - found on her arms, abdomen, chest, neck and head - would only have occurred if she had fallen repeatedly on the welder. A DA's Office press release on Foley's autopsy states she died from internal bleeding as a result of severe blunt force trauma consistent with being forcefully struck with a hand. This week Fred Cozad and friends of the family said they saw blood on the welder, but Frasier said this can't be the case. He added that investigators took photographs of the welder, which show no proof of Fred Cozad's theory.

 "There wasn't any blood; there wasn't any tissue; there was no evidence on that welder to indicate she fell on it," Frasier said. "It wasn't the cause death."

He added that Fred Cozad's claims law enforcement did not maintain a secure crime scene and that Foley was alive when emergency responders arrived at the  63469 Third Road home, don't fit. The body was cold to the touch when the ambulance crew arrived. Frasier said an officer stayed at the door during the entire investigation at the house and kept a list of those who entered and exited the home.
